I thought the original e2e question on skipping EEPROM in u-boot was addressed. The current issue is in kernel boot up process, as reported in this e2e. https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1360910/am625-q1-board-boot-loops-during-kernel-load

Forum Post: RE: SK-AM69: Which processor SDK RTOS should I use?
Hi Parth, Thanks for the reply. I noticed that the SD card demo that ships with the board has binaries that it says it is loading and running for the RTOS cores. How can I modify the behavior of these binaries? Can I just use binaries that I generate from the TDA4VH SDK RTOS? Dallin

Kallikuppa: perhaps an additional followup question to this would be: how easy would it be to convert an R5 FreeRTOS only MCU+SDK peripheral driver into an A53 Linux peripheral driver? (I know the EQEP peripheral drivers are only out there for the R5; while others may not make sense to even do, as the MCU+SDK USB drivers versus what embedded Linux has already for A53 USB drivers) thanks Jim Mrowca

Forum Post: RE: SK-AM62A-LP: 'cryptodev': Cannot allocate memory
Hi Kim, I think it might take longer to figure out the problem, so I am taking a different approach here - instead of using falcon mode, using normal boot mode from eMMC but without some optimization, I think we can reach the 10 seconds boot target. Following log shows booting SK-AM62x from SD card takes about 13.3 seconds, with the following optimization: - added "quiet" to bootargs to suppress most kernel boot logs; - removed /etc/systemd/system/multi-user.target.wants/gplv3-notice.service [2024-05-16 14:07:13.191] U-Boot SPL 2023.04-00003-g3fe6aef56587 (May 14 2024 - 14:08:28 -0500) [2024-05-16 14:07:13.207] SYSFW ABI: 3.1 (firmware rev 0x0009 '9.1.8--v09.01.08 (Kool Koala)') [2024-05-16 14:07:13.255] am62a_init: board_init_f done [2024-05-16 14:07:13.255] SPL initial stack usage: 17040 bytes [2024-05-16 14:07:13.255] am62a_init: spl_boot_device: devstat = 0x243 bootmedia = 0x8 bootindex = 0 [2024-05-16 14:07:13.271] Trying to boot from MMC2 [2024-05-16 14:07:13.367] Warning: Detected image signing certificate on GP device.

Forum Post: RE: AM3358: Suggest suitable JTAG Emulators
I'm not sure what devices and debuggers are currently supported by CCS. I will assign to the CCS team so they can answer. The 14-pin JTAG connector was more common a few years ago, but the 20-pin has become more common recently. The 14-pin connector on the debugger should have all of the signals you need for basic debug functions. You just need to build or buy an adapter to convert the 14-pin connector to a 20-pin connector.
